Description

The present invention relates to a stainless steel exterior member.

Conventionally, a long exterior member attached to the outside of a vehicle body is known. Such an exterior member is attached to the peripheral edge of the window glass of the vehicle, the peripheral edge of the roof, the edge or surface of the door, or the like for the purpose of protecting or decorating the member of the vehicle body.

Various materials are known for exterior members, but in recent years, stainless steel exterior members have become increasingly popular because they are excellent in mechanical strength, weather resistance, etc., and can give a high-gloss texture.

The stainless steel exterior member is generally groove-shaped, and both ends are often open (for example, Patent Document 1). However, a structure with an open end may not be preferred because it is less aesthetically pleasing, especially when the exterior member is mounted so that the end is noticeable.

Japanese Unexamined Patent Publication No. 2008-1122

In the conventional exterior member described in Patent Document 1, since the end portion is open, the vehicle body member, the resin material, and the like arranged under the exterior member are exposed. Therefore, when the vehicle body is viewed at an angle at which the end portion of the exterior member can be seen, it may be felt that the appearance is not good.

Therefore, a wall portion (end wall) for covering the end portion may be separately formed and attached to the end portion (FIG. 11). However, in such an exterior member 110A, a visual discomfort may occur due to the difference in texture between the exterior member main body and the end wall. In addition, it is costly to manufacture and attach a separate end wall.

It is also conceivable to form an end wall by extending a part of the exterior member and bending the part. However, in the exterior member formed in this way, wrinkles, cracks, surface distortion, and the like occur, so that the shape retention of the exterior member deteriorates. When the shape retention of the exterior member is lowered, there is a problem that the exterior member is easily deformed at the time of transportation, attachment to the vehicle body, or the like. Further, if wrinkles, cracks, surface distortion, etc. occur in the exterior member, the aesthetics may be impaired. Further, if an attempt is made to form the surface so as not to cause wrinkles, cracks, surface distortion, etc., the end wall and the side wall have a low shape, and the shape retention of the exterior member may be impaired.

Therefore, there is an increasing demand for stainless steel exterior members whose ends are more beautifully formed.

In view of the above points, it is an object of one aspect of the present invention to provide an inexpensive stainless steel exterior member having high aesthetics and high shape retention.

In order to solve the above problems, in one aspect of the present invention, a long groove-shaped stainless steel exterior member attached to the outside of the vehicle body is integrally molded on the peripheral edge of the glass plate together with a resin frame. A framed glass plate, wherein the groove of the stainless steel exterior member comprises a bottom surface, an end wall, and two side walls that are continuously and integrally formed at at least one end. When viewed in a cross section cut along a plane parallel to the surface of the end wall, the length of the line segment connecting the edges of the two side walls is F, and the length of the line segment orthogonal to the line segment is from the line segment to the bottom surface of the groove. maximum lengths is D extending into, within a range of from the inner surface of the end wall to a position spaced 10mm in the longitudinal direction, the value of D / F is Ri der 0.27 to 0.80, wherein There is no notch in the side wall within a range of 50 mm away from the inner surface of the end wall in the longitudinal direction .

According to one aspect of the present invention, a stainless steel exterior member having high aesthetics, high shape retention, and lower cost is provided.

Hereinafter, embodiments for carrying out the present invention will be described, but the present invention is not limited to the following embodiments.

<Body>
FIG. 1 illustrates a vehicle using an exterior member according to an embodiment of the present invention. The vehicle body 2 of the vehicle 1 of FIG. 1 has a front side door 7 and a rear side door 8. The front side door 7 is provided with the front side glass 4, the rear side door 8 is provided with the rear side glass 5, the rear quarter glass 6 is provided behind the rear side glass 5, and the front bench glass 4 is provided in front of the front side glass 4. There is. In the example of FIG. 1, exterior members 10a to 10d are arranged along the window frame provided with the front bench glass 3, the front side glass 4, the rear side glass 5, and the rear quarter glass 6, respectively. Further, exterior members 10e and 10f are arranged on the front side door 7 and the rear side door 8, respectively.

The exterior member 10 can be attached to the outside of the vehicle body 2 after the vehicle body 2 is manufactured. For example, a glass plate can be adhered to a vehicle body, a frame body (gasket, molding, weather strip, etc.) is provided around the glass plate, and then the frame body can be arranged so as to cover the frame body.

Further, a unit obtained by mounting the exterior member 10 on a module assembly window (MAW (registered trademark)) obtained by integrally molding a resin frame on the peripheral edge of a glass plate. Can be assembled to the window frame of the vehicle body. Further, when manufacturing the MAW, the exterior member 10 can be integrally molded with the resin frame on the peripheral portion of the glass plate.

<Module assembly window (MAW)>
FIG. 2 shows a front view of the MAW 40 incorporating a stainless steel exterior member according to an embodiment of the present invention. FIG. 2 shows the MAW 40 applied as the rear quarter glass 6 (FIG. 1) as an example.

The MAW 40 is a glass plate with a frame including a glass plate G and a frame 50 attached to the peripheral edge of the glass plate G. The frame body 50 is made of synthetic resin or the like, and can be attached so as to surround the entire circumference of the glass plate G. Further, a stainless steel exterior member 10d is attached to the outside of the frame body 50, and the exterior member 10d is integrally molded together with the glass plate G and the frame body 50.

Such integral molding of MAW40 can be manufactured by mounting a glass plate G and an exterior member 10d on a mold having a cavity corresponding to the shape of the frame body 50 and injecting a synthetic resin into the cavity. can.

FIG. 3 shows a cross-sectional view of the MAW 40 cut along the line I-I of FIG. The exterior member 10d has a long groove shape as described later, and has a substantially C-shaped or substantially L-shaped cross-sectional shape. In the example of FIG. 3, the exterior member 10 has a substantially C-shape, but a part of the C-shaped end edge (side wall to be described later) is buried in a frame body 50 made of resin or the like.

<Overall composition of exterior members>
FIG. 4 shows an overall view of a stainless steel exterior member (also referred to as a SUS molding or a stainless molding) according to an embodiment of the present invention. FIG. 4 shows, as an example, an exterior member 10d arranged along a window frame to which the rear quarter glass 6 (FIG. 1) is attached.

The exterior member 10 may have a long groove shape, and the shape as a whole is not particularly limited. The overall shape of the exterior member 10 may be designed according to the portion of the vehicle body to which the exterior member 10 is attached, and may be linear, bent or curved. When mounted along the window frame of the rear quarter glass 6, the external shape of the exterior member 10 may be a substantially L-shape (or a substantially C-shape) as in the example of FIG.

<Structure of the end of the exterior member>
5 and 6 show an enlarged perspective view of a portion including one end portion 15 of the exterior member 10 according to the embodiment of the present invention. 5 and 6 are perspective views of a portion of the same exterior member including one end 15 as viewed from different angles. Further, FIG. 7 is a bottom view of the exterior member 10 shown in FIG. 6 as viewed from the groove side (from the direction indicated by the arrow A), and FIG. 8 is a bottom view of the exterior member 10 shown in FIG. 6 from the side surface (arrow B). It is a side view (from the direction shown).

As is clear from FIG. 6, the exterior member 10 has a groove shape at the end portion 15. This groove shape is formed by a bottom surface 22, an end wall 24, a first side wall 26, and a second wall portion 28 (sometimes collectively referred to as a wall portion), and these wall portions are formed from the bottom surface 22. It extends in the same direction (upward in FIG. 6).

The bottom surface 22, the end wall 24, the first side wall 26, and the second side wall 28 are continuously and integrally formed. That is, the bottom surface 22, the end wall 24, the first side wall 26, and the second side wall 28 are joined to each other. Then, between the bottom surface 22 and the end wall 24, between the bottom surface 22 and the first side wall 26, between the bottom surface 22 and the second side wall 28, between the first side wall 26 and the end wall 24, and the second side wall. Each of the joints between the 28 and the end wall 24 is not formed by joining a plurality of members by welding or the like, but is integrally formed from a single plate-like body.

When the exterior member is manufactured from one plate-shaped body, conventionally, the end wall is formed by bending the end portion of the exterior member. However, in the exterior member formed in this way, wrinkles, cracks, surface distortion, etc. may occur on the first side wall and / or the second side wall in the vicinity of the end wall, and the aesthetic appearance may be impaired. .. Further, an exterior member 110B in which an end wall is formed by extending a part of the exterior member and bending the portion is also conceivable. However, since the exterior member 110B has a notch on the side wall (FIG. 12), it gives the impression that the end wall is separated from the main body of the exterior member, which may impair the aesthetic appearance.

On the other hand, in this embodiment, in the vicinity of the end wall 24, the first side wall 26 and / or the second side wall 28 has no wrinkles or cracks, and the first side wall 26 and / or the second side wall 28 is provided with a notch. No. For example, it is preferable that the first side wall 26 and / or the second side wall 28 has no wrinkles, cracks, or notches in a range of 50 mm, 10 mm, or 5 mm away from the inner surface of the end wall 24. Since there are no wrinkles, cracks, surface distortions, or notches on the side wall, it is possible to obtain an integrated appearance in which the side wall and the end wall are continuously transferred, and the aesthetic appearance of the end portion of the exterior member can be enhanced.

However, in a range other than the vicinity of the end portion 15, for example, in the vicinity of the center of the long overall shape of the exterior member 10, notches and holes are provided in the first side wall 26 and the second side wall 28 depending on the design and application of the exterior member 10. It can also be formed.

The heights of the end wall 24, the first side wall 26, and the second side wall 28 may or may not be the same. Further, the height of each wall portion may change depending on the location. For example, as shown in FIG. 6, the height of the first side wall 26 at the end 15 does not have to be constant. In the illustrated example, the height of the first side wall 26 is highest at the transition portion with the end wall 24, decreases as the distance from the end wall 24 increases, and is constant at a height lower than the end wall 24 in a further range. It has become. Here, the height of the wall portion (end wall 24, first side wall 26, and second side wall 28) refers to the height from the bottom surface 22. Specifically, when the bottom surface 22 is a flat surface or includes a flat surface, the length from the flat surface to the edges 24a, 26a, 28a of each wall portion can be set. When the bottom surface 22 is a curved surface, the length can be from the tangential plane in contact with the bottom surface 22 at the center of the groove to the edges 24a, 26a, 28a of each wall portion.

The end wall 24 can be equal to or higher than the height of the first side wall 26 and / or the second side wall 28. Further, the height may be equal to or higher than the height of the first side wall 26 and / or the second side wall 28 at the highest position. As a result, the end portion 15 can be covered, and it is possible to prevent the frame body or the like arranged under the exterior member 15 from being exposed and impairing the aesthetics. In the illustrated example, at the end portion 15, the height of the end wall 24 is the same as the height of the first side wall 26 at the highest position (height at the joint with the end wall 24).

The height of the end wall 24 varies depending on the overall size of the exterior member 10, but can be 3 to 25 mm at the highest position. Further, it can be 5 mm or more, more than 7 mm, and more than 8 mm. Further, in this embodiment, since each wall portion is continuously integrated, even if the height of the end wall 24 is increased, an unnecessary force is applied to the end wall 24, and the end wall 24 and the bottom surface 22 It is possible to prevent the end wall 24 from being damaged due to the concentration of stress between the ends, and the end portion 15 can be formed robustly.

Further, in the illustrated example, the edge portion 24a of the end wall 24 extends linearly, but may protrude upward or may be recessed downward. The same applies to the edges of the first side wall 26 and the second side wall 28.

The angle of the end wall 24 with respect to the bottom surface 22 is preferably 75 to 115 °, more preferably 85 to 105 °. Further, it is preferable that the end wall 24 extends so as to be substantially orthogonal to the bottom surface 22. The above angles are the side view from the side of one side wall, for example, the side view from the side of the first side wall 26, the lower contour line L1 extending in the longitudinal direction of the first side wall 26, and the longitudinal direction. It can be an angle formed by the contour line L2 extending in a direction orthogonal to. FIG. 8 shows an angle α formed by the contour line L1 extending in the longitudinal direction of the first side wall 26 and the contour line L2 extending in the direction orthogonal to the longitudinal direction.

When a plurality of exterior members are provided in the vehicle body, the ends of the exterior members are arranged so as to face each other so that the plurality of exterior members are connected to form one long member when viewed from a distance. For example, as shown in FIG. 1, the exterior member 10d provided on the peripheral edge of the rear quarter glass 6 is adjacent to the exterior member 10c provided on the peripheral edge of the rear side glass 5 of the rear side door 8, and the ends of both exterior members are adjacent to each other. They are arranged to face each other. When the angle between the bottom surface 22 and at least one side wall, for example, the first side wall 26 is 75 to 115 °, the impression that the exterior member 10d and the adjacent exterior member 10c are connected is strengthened. This makes it possible to improve the design of the entire vehicle body 2.

<Cross-sectional shape of exterior member>
FIG. 9 shows a cross-sectional view taken along line II-II of FIG. 7, that is, a plane cut along a plane parallel to the plane on which the end wall 24 extends.

The II-II line cross section of the exterior member 10 is concave. Further, although the cross-sectional shape shown in FIG. 9 is asymmetrical, the cross-sectional shape of the exterior member 10 may be symmetrical depending on the mounting location, application, and the like.

In the present embodiment, the groove of the exterior member 10 has a predetermined depth in the vicinity of at least one end portion 15. Here, the vicinity of the end portion 15 is a range 17 from the inner surface of the end wall 24 to a position 10 mm away from the inner surface in the longitudinal direction, as is schematically shown in FIG. As shown in FIG. 9, the predetermined depth is the length of the line segment connecting the edge portion 26a of the first side wall 26 and the edge portion 28a of the second side wall 28 as F, and is orthogonal to this line segment. And, when the maximum length extending from this line segment to the bottom surface (outer surface) 22 of the groove is D, the value [-] obtained by dividing D by F (hereinafter, may be referred to as solid depth) is 0. It means that it is 27 to 0.80. Specifically, F can be the length of a line segment connecting the edge portion 26a of the first side wall 26 and the edge portion 28a of the second side wall 28.

The value obtained by dividing the above D by F, that is, the D / F value is preferably 0.40 or more, and more preferably 0.50 or more. Although there is no upper limit to the D / F value, it is preferably 0.80 or less in consideration of manufacturing restrictions and costs.

Further, the D / F value measured within a range of 5 mm away from the inner surface of the end wall 24 in the longitudinal direction can be 0.27 to 0.80. Also in this case, the D / F value is more preferably 0.40 or more, and further preferably 0.50 or more.

A large D / F value means that the groove-shaped groove has a deep depth with respect to the opening width. Further, a large D / F value also means that the heights of the side walls 26 and 28 are high. Therefore, when trying to form a groove shape having a continuously integrated wall portion at the end portion 15, it can be said that the larger the D / F value, the more difficult it is to form the groove shape. The fact that the D / F value in the range near the end 24 is relatively large means that there is no place where the depth with respect to the opening width of the groove is shallow and there is no place where the side walls 26 and 28 are low in the vicinity of the end wall 24. I can say.

In this embodiment, by setting the D / F value in the vicinity of the end portion 24 to 0.27 or more, the heights of the side walls 26 and 28 are adjusted to at least the joint portion with the end wall 24 in accordance with the height of the end wall 24. Can be raised in the vicinity. Therefore, an integral wall portion having a relatively high height following the side walls 26 and 28 can be formed at the end portion 15, giving the impression that the end wall 24 is separated from the main body of the exterior member 10. It can be avoided. Further, since a separate member is not used for the end wall 24, the exterior member 10 can be formed from the main body to the end portion 15 with substantially the same texture. As a result, the appearance of stainless steel can be utilized even in the region of the end portion 15 of the exterior member 10, and the aesthetics can be improved. Further, since an integral wall portion having a relatively high height following the side walls 26 and 28 can be formed at the end portion 15, the shape retention of the exterior member 10 can be improved, and during transportation. It is possible to prevent the exterior member 10 from being deformed when it is attached to the vehicle body or the vehicle body.

Further, since the heights of the side walls 26 and 28 can be made relatively high, an advantageous effect at the time of mounting can be obtained. For example, when the exterior member 10 is integrally molded with the glass plate and the frame to form a MAW, the side walls 26 and 28 of the exterior member 10 can be deeply bitten into the frame made of resin or the like (FIG. 3). .. As a result, the exterior member 10 can be more reliably incorporated into the MAW, so that the exterior member 10 is less likely to come off even when an impact is received. Further, since the heights of the side walls 26 and 28 can be made relatively high, the rigidity of the exterior member 10 is increased, so that the rigidity when the exterior member 10 is integrally molded with the glass plate and the frame to form a MAW can also be increased. It becomes.

The values of F and D are appropriately determined depending on the mounting location, application, etc., but the value of D is preferably 3 to 18 mm, more preferably 3.5 to 15 mm, and 4 to 13 mm. Is more preferable. The value of F is preferably 5 to 40 mm, more preferably 8 to 30 mm, and even more preferably 10 to 20 mm.

The angle between the bottom surface 22 and at least one side wall, for example, the first side wall 26 can be 75 to 115 °, more preferably 85 to 95 °. The angle formed by the bottom surface 22 and the first side wall 26 is viewed as a cross section cut by a line parallel to the direction in which the surface of the end wall 24 extends when the bottom surface 22 is a flat surface or includes a flat surface. Therefore, the angle formed by the plane and the first side wall 26 can be formed. FIG. 9 shows the angle β formed by the bottom surface 22 and the first side wall 26.

When the angle between the bottom surface 22 and at least one side wall, for example, the first side wall 26 is 75 to 115 °, for example, when the exterior member 10 is integrally molded with the glass plate and the frame to form a MAW, the exterior The side walls 26 and 28 of the member 10 can be deeply bitten into a frame made of resin or the like (FIG. 3). As a result, the exterior member 10 can be more reliably incorporated into the MAW, so that the exterior member 10 is less likely to come off even when an impact is received, which is preferable.

The exterior member 10 has a groove-shaped structure formed at at least one end portion 15, but the other end portion of the long exterior member 10 depends on the location and purpose to which the exterior member 10 is attached. May also have the above configuration. In that case, the configurations of the grooves at both ends may be the same or different.

The stainless steel used for the exterior member 10 of the present embodiment is not particularly limited and may be austenitic or ferritic. Specific examples of the steel type include NK-430MA, NK-436L-NB, SUS430, SUS304 and the like. The thickness of the plate used for molding the exterior member 10 is about 0.1 to 0.7 mm, and may be about 0.2 to 0.6 mm. When it is 0.4 to 0.5 mm, a general-purpose stainless steel plate material can be used for manufacturing the exterior member 10, which is preferable.

FIG. 10 shows a cross-sectional view of the exterior member 810 according to another embodiment of the present invention. FIG. 10 is a cross-sectional view cut along a surface parallel to the surface of the end wall 24 in the vicinity of the end wall 24, that is, a position 10 mm away from the inner surface of the end wall 24, as in the cross-sectional view of FIG. be.

In the example of FIG. 9, the cross-sectional shape was specifically a substantially C-shape, but as in the example of FIG. 10, the cross-sectional shape may be a substantially L-shape. In this case, the bottom surface 822 is a recessed portion formed between the first side wall 826 and the second side wall 828.

Also in the example of FIG. 10, the groove of the exterior member 810 has a predetermined depth in the vicinity of at least one end portion. As shown in FIG. 10, the predetermined depth is defined as the length of the line segment connecting the edge portion 826a of the first side wall 826 and the edge portion 828a of the second side wall 828 as F, and is orthogonal to this line segment. And, when the maximum length extending from this line segment to the bottom surface (outer surface) 822 of the groove is D, the value [-] obtained by dividing D by F is 0.27 to 0.80. .. Specifically, F can be the length of a line segment connecting the edge portion 826a of the first side wall 826 and the outer edge 828a of the second side wall 828.

Similar to the example of FIG. 9, the D / F value is preferably 0.40 or more, and more preferably 0.50 or more. There is no upper limit to the D / F value, but it is preferably 0.80 or less in consideration of manufacturing cost and labor.

Further, the D / F value measured within a range of 5 mm away from the inner surface of the end wall 24 in the longitudinal direction can be 0.27 to 0.80. Also in this case, the D / F value is more preferably 0.40 or more, and further preferably 0.50 or more.

Other configurations of the exterior member 810 shown in FIG. 10 are the same as those described above in the exterior member 10 (FIG. 9). Further, also in the exterior member 810, by setting the D / F value in the above range, the same effect as that described above can be obtained for the exterior member 10.

<Manufacturing of exterior parts>
The exterior member 10 according to this embodiment can be manufactured by using a method of forming a stainless steel plate. For example, it can be performed by press working to deform one plate by applying pressure. Pressing is generally a processing method in which drawing is performed by drawing (deep drawing), overhanging, bending, and a combination thereof.

Molding is preferably performed by a foam method using a punch and a die. Further, in the press molding, it is preferable to perform the press molding while pressing the end portion of the material thin plate or fixing the end portion. As a result, the above-mentioned exterior member 10 can be manufactured without causing wrinkles or cracks.
